Book excerpt: A program of strange particle electroproduction off the proton using the CEBAF Large Acceptance Spectrometer (CLAS) in Hall B at Jefferson Lab is maturing and producing significant new results. This talk will focus on our most recent electroproduction results for electron beam energies up to 6 GeV covering the full range in cos {theta}*{sub K}, Q{sup 2} from 0.5 to 3.5 (GeV/c){sup 2} and W from threshold to 3.0 GeV for both K{sup +}{Lambda} and K{sup +}{Sigma}0 final states. These include measurements of cross sections and the separation of unpolarized structure functions {sigma}{sub T}, {sigma}{sub L}, {sigma}{sub LT}, and {sigma}{sub TT} as well as the polarized beam structure function {sigma}LT{prime} and beam-hyperon double polarization observables. By measuring these observables over a broad range of kinematics and combining them with complementary photoproduction results, a better picture of the underlying strangeness production mechanism can be obtained. These results can be interpreted within the framework of hadrodynamic models to measure the contributions of resonant and non-resonant amplitudes in the production process and provide a valuable tool to search for missing resonances.

Download or read book Strange Quarks In Hadrons Nuclei And Nuclear Matter Proceedings Of The International Workshop written by Kenneth H Hicks and published by World Scientific. This book was released on 2001-02-28 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume brings together the contributions of experts from different fields within the nuclear physics community. Topics such as rare kaon decays, astrophysics, relativistic heavy ion collisions, and few-GeV electromagnetic probes are covered. The strange quark plays a vital role in understanding such diverse phenomena as CP violation (article by Lincoln Wolfenstein), the “spin crisis” (article by Brad Filipone), and supernova explosions (article by Chris Fryer). Additional topics of interest are parity violation experiments, strangeness content of the proton, and enhanced strangeness production at CERN and RHIC. This unique blend of recent results, with a focus on the role of the strange quark, shows the prominence of strangeness in nuclear physics over the past 50 years.

Download or read book Polarized Structure Function Sigma lt for Kaon Electroproduction in the Nucleon Resonance Region written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The first measurements of the polarized structure function $\sigma_{LT'}$ for the reaction $p(\vec e, e'K^+)\Lambda$ in the nucleon resonance region are reported. Measurements are included from threshold up to $W$=2.05~GeV for central values of $Q^2$ of 0.65 and 1.00~GeV$^2$, and nearly the entire kaon center-of-mass angular range. $\sigma_{LT'}$ is the imaginary part of the longitudinal-transverse response and is expected to be sensitive to interferences between competing intermediate $s$-channel resonances, as well as resonant and non-resonant processes. The results for $\sigma_{LT'}$ are comparable in magnitude to previously reported results from CLAS for $\sigma_{LT}$, the real part of the same response. An intriguing sign change in $\sigma_{LT'}$ is observed in the high $Q^2$ data at $W\approx 1.9$~GeV. Comparisons to several existing model predictions are shown.

Download or read book Hadron Spectroscopy and the Confinement Problem written by D.V. Bugg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: This meeting on Hadron Spectroscopy and the Confinement Problem took place from June 27 to July 8, 1995. The first four days were at Queen Mary and Westfield College, London and the last six at the University College of Swansea, Wales. The reason for the split sites was a question of accomodating the 54 students and 12 lecturers. However, it was enjoyed by all concerned, providing the opportunity to sample the nightlife of London one week and enjoy the delightful coastal area around Swansea the following week. The meeting immediately preceded the Hadron '95 conference in Manchester. The contents of this volume run roughly parallel to the order of the lectures. Martin Faessler's brief and that of Madjid Boutemeur was to review experimental tech niques as well as physics results. We have tried to review all the areas which are currently active experimentally. This means mostly Light Meson Spectroscopy. However, Simon Capstick gave us a welcome review of Baryon Spectroscopy and the coming CEBAF program. This is an opportunity to thank NATO for their generous financial support, and also the two host institutions for excellent coordination and an enjoyable stay.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on the proceedings of the International Symposium on "Strangeness in Nuclear and Hadronic Systems (SENDAI08)," which is the third in a series of symposia on nuclear physics involving strangeness following SENDAI98 and SENDAI03. With the expectation of the completion of new accelerator facilities such as J-PARC and other new experimental facilities, recent theoretical and experimental results and future prospects of strangeness nuclear physics are discussed in great depth by leading experts of the field. The topics involved are electromagnetic production of strangeness, structure and decay of hypernuclei, hyperon-nucleon and hyperon-hyperon interactions, among others. It will also serve as a good textbook for studying the current status of strangeness in nuclear and hadronic physics.
